SMYR

UNASIS Cam Follower and Yoke Roller Bearings are designed and manufactured to the highest possible quality. These bearings offer an economic solution to industry standard principle dimensions, so they are interchangeable and readily available. Improvements have been made so you can enjoy better performance and a longer operating life.

 

The SMYR range has a cage which evenly spaces the needles during operation and offers corrosion resistance characteristics due to the Stainless Steel construction.

 

Please review the product table below to find the best bearing for your application. If you require further assistance, please reach out to our bearing engineers for tailored support.
